And even if you don't specify -S, 'less' will jump into that mode
anyway as soon as you hit the right array.  It starts out wrapping,
but hit the right arrow and it undoes the wrap.  So I often do hit '1'
right arrow to get out of the wrap situation described above.  I do
lose the leftmost character on the screen.  Then you can left-arrow
all the way back to the left, and it jumps back into wrap mode.

Pretty darn useful at times.  Now, if I could just find a way to tell
'less' after-the-fact "pretend I started you up with the -X flag".
Once I find the part I want, I want to quit the pager without clearing
that stuff off of the screen.  Sometimes.
